Yeah, you don't need the weight of the housing with the Contours. They're pretty darn rugged.

If you can move it up a bit, you'll get a slightly higher perspective and get the fork crown out of the bottom of your shot. Cables will still be an issue, though. Before I put my Leffty on, I had a mass of cables in the shot that made me run it as a helmet mount mostly. A bonus of the Lefty was that it moved all the cables to the other side, leaving a clear view forward.

don't bother with the helmet mount, it's crappy.. better off with the "profile" mount and put it just above the temple of your helmet... I actually zip tied it .. had to notch out little spots so the Cam can slide by the ties but it's much better and firmer mounting. WAY better and tighter to your head also. Issue is most regular bike helmets aren't made rigid, they use a "cage" in the rear and it allows the helmet and cam to bobble a bit.. unless you are using a full face.

Also having a cable or a bit of the fork isn't bad, give perspective and interest to the wide angle vids which is highly lacking, but it is nice to have very little of it on an edge.. I get too much myself and thing I'm going to add something to pad the flex mount out another 1/2-1 inch to have the tire and maybe a cable off to just the very edge of the shot....
